Can you add properties to Textmesh pro shaders?

Hi I was wondering if it’s possible to edit textmesh pro shaders fully.

I seem to be able edit anything in the subshader, but I don’t seem to be able to add or edit properties?

I think it’s got something to do with this line…

CustomEditor “TMPro.EditorUtilities.TMP_SDFShaderGUI”

Is there anything I can do?

The custom editor does indeed not support additional properties. It only shows those shader properties that the custom editor knows to expect. If you want to add more properties, you either need to write another custom editor that supports those, or remove the custom editor entirely.
